Thumbnail Filmstrip of 2001-2004 6.6L LB7 Duramax Fuel Injection Line (Cylinders 4 & 5) Dorman 904-127 Images
For owners of a 2001-2004 GM 6.6L Duramax LB7, a failing fuel injection line is more than just a leak; it's a significant threat to your entire fuel system. The original factory lines are prone to corrosion and contamination, which can introduce harmful debris into new, expensive fuel injectors. This contamination can cause internal damage, leading to poor performance, misfires, or even complete injector failure. The Dorman 904-127 Fuel Injection Line is a purpose-built solution designed as a direct replacement for your aging lines, specifically for cylinders #4 and #5. By replacing your old, contaminated lines with Dorman's high-quality stainless steel lines, you're not just fixing a leak—you're restoring the proper operation of your fuel system and protecting your new injector investment from premature failure.
- Direct-Fit Design: Engineered to be a perfect, direct-fit replacement for the original fuel injection line, making installation straightforward and hassle-free.
- Corrosion-Resistant Material: Constructed from durable stainless steel, offering superior resistance to corrosion and contamination compared to the factory lines.
- Precision Engineered: Designed with precise fitting inlet and outlet thread sizes (M14-1.50) and a maximum pressure rating of 40,000 psi, ensuring a secure, leak-free connection.
- OE-Equivalent: Replaces GM OE Part # 97188722, guaranteeing compatibility and a fit that meets or exceeds original equipment specifications.
- Sold Individually: This line is sold individually and is specifically designed for cylinders #4 and #5.
Don't let a small, corroded line compromise the integrity of your Duramax LB7's fuel system. The Dorman 904-127 Fuel Injection Line is a critical component for anyone replacing their fuel injectors or looking to prevent future fuel system issues. Its robust, stainless steel construction and precise specifications ensure that fuel is delivered cleanly and efficiently, restoring your engine's performance and providing you with the peace of mind that comes from knowing your fuel system is protected
